Brief Introduction Of The Roller

Rollers are important components of belt conveyors, with many types and large quantities. It accounts for 35% of the total cost of a belt conveyor and produces more than 70% resistance, so the quality of the rollers is particularly important.

Introduction of the main classification of rollers
1. According to the material, it is divided into rubber roller, ceramic roller, nylon roller and insulated roller.
2. There are mainly grooved roller sets, various types of parallel roller sets, various types of self-aligning roller sets, and various types of buffer roller sets.
(1) The trough-shaped idler has a common type of idler, a forward-tilt type idler, a quick-change type bearing type idler, a hanging type idler, a three-chain idler, a reversible idler, a grooved angle type idler, and a transition type. Roller, V-roller, etc.;
(2) Parallel idlers include ordinary type idlers, comb type idlers, forward-tilt type idlers, steel-type idlers, spiral idlers, etc.;
(3) The self-aligning roller has a universal type, a friction reversible type idler, a strong type idler, a cone idler, a spiral type idler, a combined type idler, and the like;
(4) The buffer roller has a spring plate type idler, a buffer ring type idler, a strong buffer type idler, an adjustable elastic type idler, a hanging type idler, and the like;

The importance of roller accessories

Roller accessories
The manufacturing process of the roller accessories will affect the dynamic load of the roller. The basic reason for the dynamic load is the uneven wall thickness of the roller shell and the mass imbalance caused by the radial runout of the casing. Today, I will share with you the importance of roller accessories. The analysis is as follows:
To ensure the quality of the processing and assembly of the rollers, the key is to find a roller manufacturer with strong technical strength, perfect technical equipment, scientific management and good service awareness. The manufacturer should be able to provide users with calculations from the design. , roller selection, economic and technical analysis to the complete technical service of the whole machine design.
The roller accessory can play an important role and value in the use of the roller, and can assist the use and maintenance of the roller, and help the user play an important role and value in maintaining the roller.
The manufacturer pointed out that the production and processing precision of the roller parts mainly refers to the concentricity of the inner holes of the outer casing and the idler and the machining precision of the axial dimensions of the parts. If the concentricity is too bad, it will cause the rolling bearing to bite, increase the resistance and reduce the service life; if the axial dimension error of the part is too large, a large axial gap will be formed, causing axial turbulence, destroying lubrication and sealing; If the installation quality is not good, the deviation will occur, the card will be bitten, the wear will be aggravated, and the service life of the roller will be greatly reduced. The manufacturer proposed how to arrange the rollers reasonably and design the appropriate roller group spacing to reduce the number of rollers, reduce the price of the whole machine, reduce the investment, operation and maintenance costs, and improve the economic efficiency. The processing technology of the roller is an important one. aspect.
